To all whom t may concern.'

Be it known that I, EMANUEL J. GRACE, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Dispensing'Mechanism; and I do hereby declare the following to be a full, clear, andexact'description of the invention, such as will enable others skilled in the art to which it appertains to Vmake andV usethe same, reference being had to the accompanying drawings, and to the Y letters of reference marked thereon, forming part ofthis specification. t This invention, relates Ato dispensing devices for dispensing grease for mot'or vehicles. n

This vinvention was originally shown and described in my Aapplication for patent filed February 25, 1921, Serial No. 447,63t ,of

which this is a divisional application.Y

The object of this invention is to provide dispensing mechanism adapted to measure the material as it is being delivered, and to provide suitable means for accurately adjusting the measuring mechanism. Also to provide means whereby the operating mechanism can be adjusted without disarranging the measuring mechanism.

These and other features of my invention are hereinafter set forth and pointed out and are illustrated in the accompanying'drawings in which:

Figure l, is a side elevation of'my improved dispensing mechanism.

Figure 2, is arplan view of the same.

Figure 3, is a central transverse section of the cover of the container tank.

v Figure 4, is a vertical central section of 4o the measuring mechanism enlarged.

In these .drawings A indicates the base, which .is provided with wheels a at one end, and with a leg a at the other end thereof.

Upon one end of the base A is placed a container B which communicates with a passage in the base A, shown in broken lines in Fig.`

l, leading to the pump C of ordinary construction, mounted on the other end of the base A. From the pump C, a tube C leads to a connection C2, to which a flexible tube .C3 is connected. .The opposite end of the flexible tube C3 lisprovided with a shut 0E vvalve c to which an L-shaped nozzle is secured. Theupper end of the container C Vthe sleeve J,to a weight K. y the ,weight K is a -verticalhollowscrew L,

is provided with an outturned flange b which y has an'open or slottedl ear bl'adapted to re.`

vceive the L-shapednozzlefl). kFrom the'connection C2 `an upright post C? extends up-` wardly and has secured thereon a journal Vbearing E', and upon the journal bearing E another post C5 extendsl upwardly. The

llangeb on the upper end of` the container is provided with a horizontalextension b2 l .through whichthe post Cvextends, andto which said post is secured by means ofv a setscrew b3. Mounted in thev bearing isan eccentric sleeve which a crankshaft G is placed. Upon this crank shaft G is a sprocket wheel g from w-hich'a chain g eX- tends to a sprocket wheelc upon the pumpk shaft c2. The e inner end of the eccentric sleeve F is provided with al circularrflange f see Fig. 4C, which is concentric with vthe axis of the crank sha-ft G, and vupon this flange f a plate II is mounted, so that when the eccentric sleeve F is rotated in its bear- Y ing E,fthe plate H'moves in unison with the shaft G. Upon theinner end of the shaft G, I secure a disc G', forV the purpose hereinafter set forth.v This discG also acts to maintain the plate II in contact with the inner fiat side e of the journal lbearing E. From the upper end of the rplate H, an arm 7L extends inwardly over'the disc Gfto 4a vertical sleeve J, which extends upwardly 85 through an opening in the lateral extension b2 of the flange-b, by which the'plateH is maintained in avertical position. Upon the upperside of the arm 71, there are ears 72, to which an armeK is'pivotedjwhich. extends ,through an opening in the' wall of Mounted in provided at its lower vendwith a thumb-nut by means of ywhich the'same -may be turned k95 when desired.l t y .l y Y p lVthin the hollowscrew a shaft M 'is' placed, upon theupper end of which a disc M issecured adapted to revolve withiuthe l upper end of the sleeve J. On the lower` ,endl of the shaft INI is secured a friction wheel N adapted to contact with the disc G thegravity of the parts acting to press the wheel N against-the disc G. Y

In order to maintain'the apparatus in' ad.-- 105 justment so that the pump C will operate'in accurate relation to Vthe measuring mechanism it is necessary -that .the chaing be maintained sufficiently taut so that there, will be no lost motion between the Acrank shaft G- p and the pump shaft o2, and for that purpose I have provided the eccentric sleeve F, which is shown in Fig. 4 in its uppermost throw. I/Vhen the chain is first put on, the-eccentric sleeve F should be turned to its lowermost throw, exactly opposite to the position in Fig. 4. VI/Vhen this is done the plate I-I and the mechanism supported thereon together with the shaft G `and disc G move downward in unison, so that tlierelative positionV of the disc Gr" and friction wheel N remain unchanged. Then as the crank shaft G is Vraised from time to time, by adjustment of the eccentric sleeve F the plate H and mechanism supported thereon will be raised in unison.`

VUpon'the extension b2 of the flange I) are' upright ears b4 to which arms P of the cover P of the container B are pivoted. The cover. I3 is provided with an extension p which extends over the vopen slotted ear b and covers and retains the L-shaped nozzle of the fieiible tube C3 therein so that when the cover is locked down by the paddock Q,

unauthorized persons cannot operate the mechanism to filch from the contents of the .mechanism against ltheft of material.

container. When the cover P is raised the tube C can be disengaged from the ear. o. This not only provides a support for the free end'of the tube C3 when not in use, but provides a secure means for locking the l the mechanism is operated while it is locked,

the material rims from the nozzle D back into the container. On the upper end of the sleeve J are placed characters to indicate the quantity of material dispensed, and on the disc h is an indicator which points'to the characters.A This arrangement may be reversed if desired.

' The bearing E isprovided with clamping ears e through which a clamping bolt (not shown) may be placed,`by means of which the Veccentric sleeve F may -be secured against accidentalrotation.
